Specification of Letters Patent.

To (LZZ whom it may concern:

Be it known that we, WILLIAM B. ORR and WILLIAM "J. McGnn, citizens of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented a new and useful Lifting-Jack and (jar-Wheel Holder, of which the following is a specification. V y

This invention relates to lifting-jacks and car-wheel holders, such as are used for the purpose of jacking up or elevating the trucks of railroad-cars and at the same time holding the wheels steady while brasses or bearin s are removed from and replaced in journa boxes and similar repairs are being made,

the objects of the invention being to simplify and improve the construction and operation of this class of devices.

I With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination oi parts,which will be hereinafter fully described, and particularly pointed out in the claims.

' the accompanying drawin s has been illustrated a simple and preferre form of the invention, it being, however, understood that no limitation is necessarily made to the o precise structural details therein exhibited, u t that changes, alterations, and modifications withinthe scope of the invention may be made when desired.

In the drawings, Figure 1 is a pers ective 3 5 view illustrating the invention applie in operative position. tional view of the'device constituting the invention.

Corresponding parts in both the figures are indicated throughout by similar characters ofreference.

The frame of the improved device comprises a pair of side members consisting of vertically-disposed plates or webs 11, provided at their upper edges with heads 22 and at their lower edges with flanges 3 3, said side members being connected near the ends thereof by means of plates 4, having inturned flanges 5 for the passage of'connectmeans, such as rivets 6, which extend through the flanges 5 and through the Webs of the side members.

Slidablyconnected with the frame is a nut 7, provided at its lower edges with recesses 8 '5 5 8, engaging the heads 2 of the side members,

' with which the said nut is thus connected in lever. or han le.

to be rea Fig. 2 is a transverse secsuch a manner that it may slide longitudinally between the ends of the frame. The threaded.aperture 9 of the nut admits the jack-screw 10, havin a head 11, which is transversely a erture for the reception, of a (Not shown.) The head 11 supports in the usual manner a swivel member 12, which is common in this class of devices, and which, if desired, may be supported by antifriction-balls. The sides of the nut are provided at their upper edges with flan cs 13, under which is seated a transversely-s idable frame provided at its inner end with a lug'l5, having a threaded perforation 16 for the passage of a set-screw (Not shown.)

17, havingla head 18, enablinglsaid set-screw adjusted by the and of the oporator.

The frame of the device is provided upon its outer side with a handle 19, whereby it may be conveniently carried.

In operation the device is supported upon two ties 20, the frame being made of such a length that it will nearly reach across two ties spaced in the usual manner. While the jack-screw is lowered, the nut may be moved to a position directly beneath the journalbox which is to be operated upon, and the set-screw 17 is screwed down until it engages a flange 21 of the wheel 22. The j ackserew is now manipulated until the journalbox is sufiiciently elevated, the wheel being in the meanwhile steadied and held upon the.

track by the set-screw 17, making it unnecessary to remove the packing from the box, said packing being compressed until the brassmay be readil removed.

By this'improve device joumal boxes of railroad-cars maybe readily and conveniently jacked up for variouspurposes. The jackscrew may be placed directly beneath the box which is to be operated upon, owing to the ion itudinai ad ustability of the nut, thus ma g it unnecessary at any time to change the position of the car for the purpose of placing the journal-box in alinement with the .jac The adjustability of the frame 14, carrying the set-screw 17, is also an important feature of the invention, since it enables the adjusted to the desired position without ever having recourse to moving the car that is to be operated upon. This is obviously important, for thereason that it is frequently necessary, as in the case of hot boxes, to operate upon a car whichis one of a train and parts of the device to be readily zoo which frequently involves much difiiculty and loss of time in hrin' ing the car to the d e sired position when orc inary lifting apparatus is used.

Having thus described the invention, what is claimed is l. A base-frame comprising side members having heads at their upper ends and flanges at their lower ends and end plates connecting said side members, in combination with a nut having grooves slidably engaging the heads of the side members, and a jack-screw engaging the nut.

i 2. A base-frame, a nut connected with and longitudinally slidahle with relation to the frame, a jack-screw carried by the nut, and. wlieel-llange-engaging means adj ustably eonnected with the nut.

23. A nut supported for longitudinal sliding movement, a jack-screw carded by the nut, a frame connected with the nut for transverse sliding movement, and a wheelflangeengagingg screw carried by said frame.

4.. A supporting-frame, a jaclescrew-carrying nut slidably connected therewith and having laterally-extending flanges, a frame slidab e transversely between said flanges and the upper edges of the side members of the supporting-frame, and a wheel-flangeengaging screw carried by said frame.

In testimony that We claim the foregoing as our own We have hereto aliixed our signatures in the presence of two witnesses.
